Abstract

Устройство для извлечения металлического лома из ствола скважины включает множество магнитных узлов, расположенных продольно по длине корпуса (10) инструмента. Каждый магнитный узел имеет магнитный элемент (42), который образует первичную зону (70) осаждения буровой мелочью. Каждый магнитный элемент защищен защитным устройством магнита. Вторичная зона осаждения буровой мелочи образована между магнитным узлом и устройством защиты магнита смежного магнитного элемента для использования остаточной магнитной силы, создаваемой магнитными элементами. При этом вторичная зона осаждения частиц занимает площадь, по меньшей мере в два раза меньшую, чем площадь первичных зон осаждения.Международная заявка была опубликована вместе с отчетом о международном поиске.A device for extracting scrap metal from a well bore includes a plurality of magnetic assemblies arranged longitudinally along the length of the tool body (10). Each magnetic assembly has a magnetic element (42), which forms the primary zone (70) of the deposition of the drilling fines. Each magnetic element is protected by a magnet protection device. The secondary precipitation zone of the drill bit is formed between the magnetic unit and the magnet protection device of the adjacent magnetic element to use the residual magnetic force created by the magnetic elements. At the same time, the secondary particle deposition zone covers an area at least two times smaller than the area of the primary deposition zones. The international application was published together with an international search report.
